"Hey guys, I've been keeping an eye on the GPU mining scene lately and the prices of mining rigs have been dropping, making it more viable than ever. I know some of us got out of the game during the crypto winter, but with the rise of Ethereum's move to Proof of Stake, do you guys think it's time to get back into GPU mining? I'm thinking of dusting off my old rig, does anyone have any thoughts on what's hot in the market right now?"
